300-445 Question 250
Select 3An enterprise network experiences frequent congestion during peak hours, impacting critical application performance. Upon analyzing traffic patterns, you notice that 70% of the traffic is non-critical file-sharing traffic. The network topology includes redundant links that are underutilized. Which of the following recommendations would optimize the network capacity and improve critical application performance?
- A
Implement Quality of Service (QoS) policies to prioritize critical application traffic over non-critical traffic.
- B
Reconfigure the network topology to utilize redundant links for non-critical traffic.
- C
Increase the available bandwidth on the primary links by upgrading the physical hardware.
- D
Remove redundant links to simplify the network and reduce congestion.
- E
Deploy traffic shaping to limit non-critical file-sharing traffic during peak hours.
Show answer and explanation
Correct answers: A, B, E
Explanation
The optimization of network capacity should focus on prioritizing critical traffic, efficiently utilizing existing resources, and limiting non-critical traffic where necessary. QoS policies ensure prioritization, reconfiguring topology balances the load, and traffic shaping limits excess non-critical traffic. These approaches collectively improve performance without incurring unnecessary costs.
- A. Correct.
Correct. Implementing QoS policies ensures that critical application traffic is prioritized, reducing the impact of congestion on these applications.
- B. Correct.
Correct. Reconfiguring the network topology to offload non-critical traffic to redundant links helps balance the load and reduces congestion on primary paths.
- C. Incorrect.
Incorrect. While increasing bandwidth may temporarily alleviate congestion, it is a costly and less efficient solution compared to optimizing traffic flows and prioritization.
- D. Incorrect.
Incorrect. Removing redundant links would reduce network resiliency and could make the network more susceptible to failures, which is not a recommended optimization.
- E. Correct.
Correct. Traffic shaping can effectively limit non-critical traffic, ensuring that critical applications have sufficient bandwidth during peak hours.
